- Ethical Subjectivism -- moral judgments are individuals' opinions
- Emotivism -- moral judgments are simply emotional responses
- Social Contract Theory
- Deontological (rule-based) theories:
- Divine Command Theory -- moral judgments are "God's will"
- Natural Law Theory -- moral judgments are "the dictates of reason"
- Kant's "Categorical Imperative": "Act only according to that
maxim by which you can at the same time will that it should become
a universal law." (Immanuel Kant, Groundwork of the Metaphysics
of Morals , 1785; cited in Rachels, 115)
- Rachels' "Morality Without Hubris": "We ought to act so as to
promote impartially the interests of everyone alike, except when
individuals deserve particular responses as a result of their own
past behavior." [James Rachels, The Elements of Moral Philosophy
(New York, etc.: McGraw-Hill, 1986), 143]
- Teleological (goal-based) theories:
- Ethical Egoism -- a moral act is what benefits me
- Utilitarianism -- a moral act is what causes the greatest amount
of happiness for the most people concerned
- i.e., 1) right actions are those that have the best consequences
- 2) in assessing #1, the amount of happiness or unhappiness
caused is the only relevant consideration (= hedonism)
- 3) each person's welfare is equally important
